In what context do you mean this?
Normally I would say its a query after an URL like;

instance 1
http://www.domain.ext/page.htm

instance 2
http://www.domain.ext/page.htm?test1

Where in 2nd instance there will be a query carried out on the page
(this can for instance been used to pass a variable to the page)

Works like this

three meanings in my 'bible'

the one you stated..URL stuff.

Then teh normal C style compact condtional as in

a=(b==c)?d:e;

(if b equals c, set a to d, else set a to e)

Or a part of a regexp pattern matching string thing.

Here? test2 contains the string "?test1". There is no "question mark
before a variable".
